Description

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.

The following security issues are addressed with this release:

An authorization flaw was discovered in Kubernetes; the API server did not properly check user permissions when handling certain requests. An authenticated remote attacker could use this flaw to gain additional access to resources such as RAM and disk space. (CVE-2016-1905)

An authorization flaw was discovered in Kubernetes; the API server did not properly check user permissions when handling certain build-configuration strategies. A remote attacker could create build configurations with strategies that violate policy. Although the attacker could not launch the build themselves (launch fails when the policy is violated), if the build configuration files were later launched by other privileged services (such as automated triggers), user privileges could be bypassed allowing attacker escalation. (CVE-2016-1906)

Space precludes documenting all of the bug fixes and enhancements in this advisory. See the OpenShift Enterprise 3.1 Release Notes, which will be updated shortly for release 3.1.1, for details about these changes:

All OpenShift Enterprise 3 users are advised to upgrade to these updated packages.
